* This EJB has 2 business interfaces: CounterRemote, a remote business
* interface, and CounterLocal, a local business interface
*
* Per EJB3 rules when the @Remote or @Local annotation isn't present
* in the bean class (this class), all interfaces are considered
* local unless explicitly annotated otherwise. If you look
* in the CounterRemote interface, you'll notice it uses the @Remote
* annotation while the CounterLocal interface is not annotated relying
